ronnnve Box.

To all whom/it may concern:

' Be it known that I, RICHARD H. Voler, a citizen of the UnitedStatesf'and resident of Milwaukee, in the county of` Milwaukee and Stateof Wisconsin, have'invented new and useful Improvements in FoldingBoxes, of which the following is a description, reference being had to AThis invention relates folding boxes.

It is one ofthe objects of the presentinvention to provide a folding boxof the type more commonly made of paper board and which is so folded inits flat form that by bending up the side portions of the box the toimprovements in endportions will be automaticallyswungto open position.andmay be v,easily interlocked in open position to said side pieces.

A. further object of ther invention is to in which the portions of thebox which are locked together will be securely held against accidentalunlocking of the parts.

A further object of the invention is to provide a folding box which isof strong and durable construction and in which the minimum amount ofstock is used.

A further ob] is to provide a folding box which may be and which may beeasily and quickly unfolded for use.

tionsof the stock,

A further object of the present invention is to provide afolding box inwhich porof which the. box is formed, are folded over upon reinforcingends or sides for the box. With the above and other objects in view, theinvention consists of the improved folding box. and its parts andcombinations as set forth in the claims, and all equivalents thereof. A

In the accompanying drawing in which the same reference charactersindicate the same parts in all of the views:

ect of the presentlinvention Q itself to form i position, a portion.

9 and upper and lower transversely extendling parallel end creases' 10and 11 which cross the' longitudinal or side creases. These folds orcreasesl divide the box blank into a bottom portion 12, endportions orwalls 14 and reinforcing end portions` or walls 15. rEhe reinforcing endportions` 15 are. provided with notches 16 forming locking flaps 16which are adapted to interlock withthe notched portions 1T rof the sideends portions 13 when the box is in open position as'shown in Figs. 2and 6.

ln order to permit the side end portions 13 being folded at an angleagainst the end portions 14, the said-side end portions are providedwith creases or folds 18 which extend diagonally at forty-five degreeangles from the four corners of the bottom portion 12 to the notches 16of the side end portions. In forming the box the side portions arefolded over upon the bottom portion and the reinforcing end portions`are then folded over upon the end portions and secured thereto bystaples 19 orother)4 desirable means. i 1

It will be noted that the inner edges of the reinforcing ends registerwith the folded side end notches so that when the end portions are bentupwardly to form the box the sides will be automatically swung upwardlyto open position due to the formation of the transverse and diagonal'creases. VVthen in open or uncollapsed position-the locking aps aresprung over the notched ortions of the side end portions of the Vlankand the box will be locked in open position. The top or cover 2O for thebox is formed in the same manner as the bottom portion and is slightlylarger in size to easily slip over bottom portion. It will also be notedthat the construction of the box provides for forming the sides ofsingle `thickness of ymaterial throughout their length.
